Question

Hello i do want a sort an array, that contains this:

String[] info = new String[5]{"6,j", "7,d", "12,s", "4,h", "14,s" };

But if i use this:

Array.Sort(info);

The output becomes:

"7,d"
"6,j"
"4,h"
"14,s"
"12,s"

But i wont the output to be:

"14,s"
"12,s"
"7,d"
"6,j"
"4,h"

What is the easiest way to do it in/with C#??

And i cant get Alphanumeric sort to work when i do like this:

Array.Sort(info, new AlphanumComparatorFast());

the type or namespace “AlphanumComparatorFast” could not be found are
you missing a using directive or an assembly reference

is the error that i get…

Answer 1

try with:

var sortedArray = info.OrderBy(s=>int.Parse(s.Split(',')[0])).ToArray();

This sorts just by the numeric part, but you can elaborate on that sample. This code strongly assumes that there is always the comma separator, this may be is an issue in production, do some more accurate error handling.
Should the array contains some elements that does not conform the exception, providing that is acceptable to ignore the failing elements, we can write:

 var sortedArray = info.Where(k=>!string.IsNullOrEmpty(k)&&k.IndexOf(",")!=-1)
.OrderBy(s=>int.Parse(s.Split(',')[0])).ToArray();
